I MPORTANT : PRIOR TO INSTALLATION
1
Installation must be carried out according to local regulations by
qualified trade persons. Isolating switch (es), shut-off valves etc must
be within easy reach of the machine for future service and
maintenance requirements. If in doubt call ES OOD AUSTRALIA or
their representative for further information. No responsibility will be
accepted for defects or damages by improper installation, for changes
to the product not authorised by ES OOD AUSTRALIA, or for
operation outside the technical specifications.
ES OOD AUSTRALIA warrants their products to be free from defects
in material and workmanship under "normal use and service". This
does not include normal wear and tear of parts. ES OOD
AUSTRALIA will repair or replace any parts, which in ES OOD
AUSTRALIA's sole judgement are defective in material or
workmanship, in accordance with the warranty offered.
This undertaking covers the provision of labour and parts for 12
months from the date of delivery to the purchaser. This undertaking
applies only to state capitals. Remote areas are not covered by this
commitment and special enquires should be made. (Note: Tr vel
time not covered by w rr nty)
In no event will ES OOD AUSTRALIA be liable for loss of facilities or
other property and such things as, but not limited to, additional labour
costs, loss of revenue or anticipated profits, and other damages of any
kind whether direct, indirect, incidental or consequential.
Labour under warranty is supplied free of charge during normal
working hours, Monday to Friday. Should warranty work be requested
outside or our normal working hours a labour charge will be applied
equivalent to a normal hour rate without out of hour’s penalty rates.
(Refer to last page of this manual for your closest branch for arranty
repair services)
Note: It is the responsibility of the owner to ensure the water feed to
Eswood Dish and Glass washers is of a quality that will not form
excessive build up of calcium and other dissolved minerals on the
heating elements. Premature failure of heating elements that exhibit
this cause of failure will not be covered under warranty, also if the filter
valve is discarded from the detergent tube warranty will be voided.
PLEASE ENSURE SUITABLE DETERGENT IS USED.

1. Remove the lower panel, position the machine and level by
screwing the adjustable feet.
2. Fit a 11/2” B.S.P. waste trap to underside of tank outlet.
3. Connect the hot water supply hose to a

” B.S.P. isolating valve
adjacent to the machine. The hot water input supply should be at
least 45

C and 200 to 400 kPa. A pressure reducing valve
should be fitted for pressure above 400 kPa.
Do not m ke w ter or plumbing connections th t will
prevent the m chine from being removed from position, for
the purpose of servicing.
Note that all plumbing work is to be done in accordance with
local plumbing codes.
4. Ensure that the rotary switch on the control panel is “OFF” and
the toggle switch behind the lower panel is set to the “install”
position. Connect the three pin plug lead to a 20 amp, 240V,
50Hz, 1 phase power outlet.

1. ith the rotary switch on the control panel “OFF”, turn the water
and power on.
2. Open the door, ensure the overflow tube is placed into the tank
drain flange and pump intake filter is located over the pump
suction hole (inside tank front) then close the door.
3. The machine is fitted with automatic detergent and rinse aid
injectors. Place the free end of the 10mm clear plastic tube for
detergent, (located under the machine), into a 4 Litre or other
suitable container of detergent. Repeat for the rinse aid line. The
unit will prime itself after the initial cycles.
The injector must not run without detergent. Use only quality
commercial dishwashing and rinse aid product in accordance
with manufacturers’ recommendations.
4. Turn the control panel rotary switch to the “FILL” position (see
page 7) and the rinse cylinder will begin to fill with water. The fill
light illuminates till the cycle is complete. hen the rinse cylinder
is full, the water will flow out of the rinse jets and fills the wash
tank and stop automatically.
This ensures that all air is expelled from the rinse cylinder and
that the heating elements are safely covered with water. F ilure
to observe the bove will c use d m ge to the elements
nd is not covered under w rr nty.
5. Open the door check that the wash tank level is within 30mm of
the overflow level. Place strainer trays in position within the
tank, close the door, and turn the toggle switch behind the lower
panel to the “Run” position.

6. Turn the rotary switch to a “CYCLE” (ie: short, medium or long)
position and depress the “START” button. The machine will not
start until the water in the rinse cylinder has reached 82
O
C, as
indicated by the “Low” temperature indicator light. At this
temperature or above, the machine will start and stop
automatically as indicated by the pulsating “CYCLE” light. (See
Control on this page).
7. Check under the machine for leaks and any loose items. Check
that the upper and lower wash arms turn freely. Note that the
indicator lights are functioning correctly.
8. At the end of the initial procedure, turn rotary switch to the ‘OFF”
position, open the door, remove the “strainer trays” and remove
the “overflow Tube” to drain tank. Place the overflow tube back
in position.
10. Refit the lower front panel and if possible leave the door open to
“Air” the machine

1. Check the level of detergent and fill when necessary. Also check
that the pump intake filter is clean and in place over tank intake
hole and the overflow tube is placed into the drain flange at
bottom of tank.
2. Close the door, turn the rotary switch to “FILL” , the fill light
illuminates till filling is complete.
3. hen the machine has finished filling, open the door and check
that the water is up to the overflow level (approx. 30mm from
tank shelf) . The wash tank heating is actuated automatically.
Place the strainer trays in place within the tank.
4. Select one of three auto cycles on the rotary switch (see page 7
) according to the degree of soiling on the dishware. For heavy
soiling use a long cycle and for light soiling use a short cycle.
5. Scrape off any loose food matter and place the dirty items in an
appropriate rack. Open the door, slide the rack into the machine,
close the door and press the “START” button. The cycle light
(see Page 7 ) pulsates during the cycle till complete.
Note that the cycle will not begin until the water in the booster
has reached 82
O
C.to ensure correct temp of operation. arning
light “low temp” (See page 7) will indicate if the temperature is
low.
hen loading racks, face the flat plates with face angled
upwards, bowls can be angled forward and the small items such
as glasses and cups to be placed upside down in the open rack.
To avoid breakages when washing stem-ware, it is advisable to
use a compartmented glass rack. Your supplier can advise you
on the selection of an appropriate rack.
6. hen the washing is finished, open the door and remove the
clean rack. To wash another rack repeat from step 5.

S HUTDOWN AND MAINTENANCE
6
1. Turn the rotary switch to “OFF“
2. Remove the strainer trays and overflow tube and drain the tank.
Clean the strainer trays by washing under tap.
3. Remove the pump intake filter at bottom of tank and clean it
under a tap ( ait till the wash water has been drained
completely before removal). Then replace the filter and overflow
tube.
4. Check that the rinse and wash arms and jets are free of foreign
matter. If necessary, remove the arms by undoing the centre
knurled screw and prick the jets using a small paper clip and
washout under tap and refit.
5. Clean the exterior of the machine with a damp sponge. Do not
pass water over the electrical controls and avoid abrasive or
strong detergents.
6. Check for leaks and ensure that the arms rotate freely.
7. Leave the door open if possible to allow the machine to air.
